Super Mario All-Stars is a collection of Super Mario platforming video games that was developed and published by Nintendo for the Super Nintendo Entertainment System in 1993. The game contains enhanced remakes of Super Mario Bros., Super Mario Bros. 2 (the previously Japanese-exclusive release, known in the United States as Super Mario Bros.: The Lost Levels), Super Mario Bros. 2 (the non-Japanese version), and Super Mario Bros. 3. The games are all developed to take advantage of the Super NES hardware, featuring updated graphics and sounds and additional save mechanisms.
The gameplay of each remade game is nearly identical to its original version, though some game physics as well as character and level designs are slightly modified, and some bugs, including the 'Minus World' in Super Mario Bros., are fixed.
The four games each feature enhanced 16-bit graphics and updated soundtracks to take advantage of the Super NES hardware, including parallax scrolling. All four games offer a save feature, which the original games lacked, allowing the player to save progress and resume play from the start of any previously accessed world (or in The Lost Levels, any previously accessed level). Up to four individual save files can be stored for each game. The games also allow the player to customize control configuration, allowing the 'jump' and 'dash' actions to be mapped to different buttons on the Super NES controller.
